Engineering Contradiction Analysis
1Measurement precision
If a capacitor-based measuring device is used to determine permittivity of materials, then measurements can be performed, but accuracy is limited for materials of higher thickness
Solution Approach 1:
The patent introduces an intermediary measurement approach using a measuring oscillator and frequency meter system that mediates between the capacitor and the material being tested. This intermediary system enables accurate measurement of permittivity for materials of various thicknesses by converting capacitance measurements into frequency readings, thereby resolving the limitation of direct capacitor-based measurements for thick materials.
Solution Approach 2:
The patent changes the measurement parameter from direct capacitance reading to frequency measurement. By using a measuring oscillator whose frequency is determined by the capacitance of the test arrangement, the system transforms the measurement into a frequency domain where thickness variations do not limit accuracy. This parameter change enables precise permittivity determination regardless of material thickness.
2Productivity
If conventional measurement methods are used for electromagnetic parameters, then measurements can be obtained, but efficiency is reduced
Solution Approach 1:
The patent implements continuous measurement capability where the measuring oscillator continuously generates signals and the frequency meter continuously reads the output. This continuous action eliminates the need for repeated manual measurements and allows for rapid determination of permittivity, significantly improving measurement efficiency and reducing time loss.
Solution Approach 2:
The patent replaces manual or mechanical measurement procedures with an automated electronic system consisting of a measuring oscillator, frequency meter, and digital display. This substitution eliminates manual intervention and mechanical operations, enabling rapid, automated measurement of electromagnetic parameters and thereby increasing productivity while reducing measurement time.
